Directions

Cook pasta according to package directions, undercooking by 2 minutes.

While pasta is cooking, melt remaining 2 tablespoons butter in a heavy saucepan over medium-low heat. Add flour and mustard; whisk 2 minutes. Add milk, whisking to combine. Increase heat to medium and bring to a boil. Simmer, still whisking, until slightly thickened, about 3 minutes. Stir in salt and pepper and remove from heat; stir in Gouda until fully combined, then stir in Cheddar and remaining Â¼ cup Parmesan.

Drain tomatoes in a strainer. Drain pasta and return to pot. Add tomatoes and pour in sauce. Stir to blend. Transfer to ramekins. Sprinkle panko mixture over tops. Bake about 20 minutes, until golden and cheese is bubbling.
